Cleaners

All metals need to be cleaned prior to electroplating, blackening, or finishing. Metalworking fluids and carbonaceous smut need to be removed in a soak, spray, electroclean, or ultrasonic cleaning. A properly cleaned part will have excellent adhesion and be brighter, blacker, and smut-free. Learn More

Hot Black Oxide Just Got Kooler

Posted by Eric Olander on July 10, 2012

EPi just recently developed a new black oxide solution called Kool Blak.

Kool-Blak is classified as a mid-temperature black oxide and it represents an impressive innovation in the world of black oxide. Kool-Blak blackens at a temperature of 220-245 degrees as opposed to hot black oxide that operates above boiling point (285 degrees). This means that Kool-Blak requires no boiling making it safer for the machine operators to use and provides considerable energy cost savings.

Another amazing attribute of Kool-Blak is its ability to blacken 100% smut free. This makes it easier for job shops, OEM manufacturers, and "do-it-yourselfers" to blacken with confidence. Kool-Blak is the newest of EPi's line of black oxide products, joining Ultra-Blak and Insta-Blak. These three hot, mid, and room temp black oxides are just a few more examples of how EPi is simply superior.
